Abstract

PURPOSE: An Internet phone calling method using an Internet terminal is provided to allow a user to easily use an Internet phone by sensing a corresponding signal when the user turns on a microphone and automatically operating an Internet phone program. CONSTITUTION: A CPU determines whether a microphone interrupt occurs(S10). If the microphone interrupt occurs, the CPU operates an Internet phone program from a ROM(S11). The CPU determines whether the other party has made a phone call to a user(S13). If the user has made a phone call to the other party, the CPU displays a phone menu(S14). The CPU displays a phone book menu(S15) and the user selects an address of the other party to be called from the phone book menu(S16). The user makes a phone call to the other party(S17) and makes a call communication with the other party by using a microphone and a speaker mounted at an Internet terminal(S18). The user terminates the call communication(S19).

Description

How to Make an Internet Call Using an Internet Terminal

The present invention relates to an internet telephone method using an internet terminal. In particular, the Internet terminal automatically detects a signal of turning on a microphone and automatically executes an internet telephone program so that even a user who does not use a computer or the internet can easily use the internet. The present invention relates to an internet telephone method using an internet terminal capable of using a telephone.

Today, with the development of the Internet and the increasing number of subscribers, it is now possible to use Internet telephony using microphones and speakers mounted on Internet terminals without using a separate telephone.

FIG. 1 is a block diagram showing the configuration of a typical Internet terminal. An audio bus interface unit is formed by encoding an audio signal input from a microphone (ROM) 3, a RAM (2) for processing data, and a microphone. (6) an audio codec (7), a host computer, a telephone network or a local area network (LAN), which transmits to the system via the audio bus interface unit 6 from the system and restores the coded audio signal to the speaker. And a network interface unit 5 connected through a network, a screen display device 4 displayed on a screen, a user interface unit 8 connected to a keyboard and a mouse, and a CPU 1 that manages the entire system.

In the method of using an Internet phone in such an Internet terminal, the user first selects an Internet phone application so that the CPU 1 operates to prepare and wait for an Internet phone transmission and reception state. In addition, when the other party calls, the user makes a call using a microphone and a speaker mounted on the Internet terminal. Meanwhile, the user clicks a call button to call the other party. Subsequently, the user types the corresponding Internet address in the menu displayed on the screen or selects the other party's address using the phone book menu and calls, and uses the microphone and the speaker to talk with the other party.

However, there was an inconvenience in that the user has to go through various steps such as finding and clicking an icon of the corresponding program with a mouse before preparing a call transmission / reception state. Accordingly, there is a problem that the Internet phone is difficult for users who are not familiar with computers or the Internet.

The present invention has been made to solve the above problems, and an object of the present invention is to operate the Internet phone application automatically in the CPU when the user turns on the microphone, so that users who do not make good use of the computer or the Internet can easily use the Internet phone. One way is to provide an internet phone call using an internet terminal.

In order to achieve the above object, the Internet telephone method using the Internet terminal according to the present invention comprises the steps of: generating a microphone interrupt signal when the user turns on the microphone power, loading the Internet telephone program by the microphone interrupt signal; And displaying a phone menu when the other party does not call, and connecting the phone by a phone menu selected by the user.

Other objects and advantages of the present invention in addition to the above objects will become apparent from the description of the embodiments of the present invention with reference to the accompanying drawings.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to FIGS. 2 to 4.

2 is a block diagram showing the configuration of an Internet terminal for explaining the Internet telephony method according to the present invention. The Internet terminal includes a ROM (3) in which an Internet program is stored, a RAM (2) for processing data, and a microcomputer. An audio codec (7) which encodes an audio signal input from the system and transmits the encoded audio signal to the system through the audio bus interface unit 6 and restores the coded audio signal transmitted from the system through the audio bus interface unit 6 to the speaker. , A network interface unit 5 connected to a host computer via a telephone network or a local area network (LAN), a screen display unit 4 displayed on a screen, a user interface unit 8 connected to a keyboard and a mouse, and the entire system. The microphone 1 and the microphone signal recognition unit 10 for detecting the microphone signal from the microphone to generate an interrupt to the CPU (1) And a.

FIG. 3 is a block diagram illustrating the microphone signal recognition unit 10 in detail in the configuration of FIG. 2. The microphone signal recognition unit 10 converts a signal input by switching on the microphone 11 to digital data. A / D converter 12 and a comparator 14 for generating an interrupt to the CPU 1 of FIG. 2 by comparing the data input from the A / D converter 12 with the value of the preset data latch 13. do. Here, if the data value from the A / D converter 12 in the comparator 14 is larger than the value of the data latch 13, a microphone interrupt is generated to the CPU 1.

4 is a flowchart illustrating an internet telephony method using an internet terminal according to the present invention, which will be described with reference to FIGS. 2 and 3.

When the user turns on the microphone 11 in order to use an Internet telephone, the signal input from the microphone 11 is converted into digital data by the A / D converter 12, and the data and the preset data latch 13 If the value is compared in the comparator 14 and the value from the A / D converter 12 is large, the comparator 14 starts by generating a microphone interrupt to the CPU 1. In the tenth step, the CPU 1 determines whether the microphone interrupt has occurred, and if it is the microphone interrupt, in the eleventh step, the CPU 1 operates the Internet telephone program from the ROM 3. On the other hand, if it is not the microphone interrupt in the tenth step, the process proceeds to the twelfth step, and the CPU 1 performs the corresponding interrupt and returns.

Then, in step 13, if it is determined that the other party is calling and the other party is not calling, that is, the user calls the other party, in step 14, the CPU 1 displays the phone menu on the screen. Subsequently, in step 15, the CPU 1 displays the phone book menu on the screen, and in step 16, the user selects the address of the other party to call from the phone book menu. Then, in step 17, the other party is called, and in step 18, the user talks with the other party using a microphone and a speaker mounted in the Internet terminal. When the user completes the call in step 19, the CPU 1 returns and returns to the original screen.

On the other hand, if the other party has made a call in step 13, the process proceeds to step 18, and after the conversation with the other party (end 19), the CPU 1 returns.

As described above, according to the present invention, when the user turns on the microphone, the Internet terminal detects the signal and automatically operates the Internet phone program, so that the user can use the Internet phone more easily. In addition, users who do not use the computer or the Internet well, there is an effect that can easily use the Internet phone.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the technical spirit of the present invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification but should be defined by the claims.
